Roller making system and method

Abstract

The present disclosure provides a roller making system for making a roller with a plurality of microstructures. The roller making system includes a coating unit to coat molten Ethylene Tetrafluoroethylene (ETFE) material onto a lateral surface of a cylindrical workpiece, to obtain a semi-finished roller with an uniform ETFE layer after the molten ETFE material is solidified, and a microstructure forming unit to machine the ETFE layer of the semi-finished roller, to form the plurality of microstructures in the ETFE layer, thereby making a finished roller with the plurality of microstructures.

What is claimed is: 
     
         1 . A roller making system for making a roller with a plurality of microstructures, the roller making system comprising:

         2 . The roller making system as described in  claim 1 , wherein the coating unit is a machine with a scraper, and the machine controls the scraper to coat the molten ETFE material onto the lateral surface of the workpiece. 
     
     
         3 . The roller making system as described in  claim 1 , wherein the coating unit is a Slot Die coating device. 
     
     
         4 . The roller making system as described in  claim 1 , wherein the microstructure forming unit machines the uniform ETFE layer with ultra-precision technology to form the plurality of microstructures. 
     
     
         5 . The roller making system as described in  claim 1 , wherein the microstructure forming unit is a roller with a plurality of protruding teeth on its lateral surface, and creates the plurality of microstructures in the ETFT layer by hot stamping. 
     
     
         6 . The roller making system as described in  claim 5 , wherein the microstructure forming unit and the semi-finished roller are both heated to approximate to  200  degrees. 
     
     
         7 . The roller making system as described in  claim 1 , wherein the temperature of the molten ETFE material is maintained between  240  degrees and  260  degrees. 
     
     
         8 . A method for making a roller with a plurality of microstructures, the making method comprising:
 coat molten Ethylene Tetrafluoroethylene (ETFE) material onto a lateral surface of a cylindrical workpiece, to obtain a semi-finished roller with an uniform ETFE layer after the molten ETFE material is solidified; and   machine the uniform ETFE layer of the semi-finished roller, to form the plurality of microstructures in the ETFE layer, thereby making a finished roller with the plurality of microstructures.   
     
     
         9 . The method as described in  claim 8 , wherein the machining step comprising:
